This show hit below $40 a while back, then increased to $60+, and now is being offered by Amazon for $40 and change. Considering the US set is still very pricey and is gimmicky (like the Lost series box set in the US vs the UK was), those who just want the show will be better off investing here.
It has a 2-4 week dispatch/ship status on it, so be prepared to be patient.
